N.J., a corporation of New Jersey Filed May 20, 1965, Ser. No. 457,357 16 Claims. (Cl. 281-29) This invention relates to album cover boards. Particularly, this invention relates to an album cover board having a panel board and a spine board of multi-layer construction. More particularly, this invention relates to an album cover board having a panel board, an integral flap on the panel board and a spine board.

In the past, album cover boards were made in a manner which required handling the spine boards and panel boards separately. Further, the panel boards were stacked in alternating fashion with flap paper portions. This manner of making an album cover board, generally known as padding, required the trimming of the stacked panel boards and flap paper portions by means of a flat cutter so that the respective edges of the panel boards and flap paper portions were fiush. Each panel board was then painted with glue on the edge where the flap paper portion was to be joined. Each panel is then supplied with a suitable padding inserted between the panel and flap paper portion. The structure is then fed into a casemaker along with a separate spine board and covered with the desired decorative paper or cloth.

The above method is cumbersome due to the handling of separate pieces which must be accurately positioned and aligned in order to achieve a neat album cover board.

Generally, this invention solves the problems of the prior art by providing an album cover board which is made as an integral unit from a continuous process. Further this invention provides an album cover board which has an integral flap paper portion jointed to the panel board portion in an accurate, neat and useful manner. The album cover board is made by generating two streams of board material from a pair of rolls, bringing the generated streams into superimposed relationship and bonding the two streams together into a single twoply stream. The two-ply stream is then slit into a single stream of twoply spine board and a single stream of twoply panel board while the edges thereof are suitably trimmed. These two streams are then spaced apart from each other while in the same horizontal plane. A continuous stream of binge material is then brought into engagement with and bonded to a lower surface portion of the panel board stream and a lower surface portion of the spine board stream. Subsequently, a continuous stream of flap paper is brought into engagement with and bonded to an upper surface portion of the panel board stream at the edge nearest to the spine board stream. The stream of flap paper is initially generated from a roll in a fiat manner. However, as the stream of flap paper approaches the stream of panel board, one edge portion of the stream of flap paper is guided into a foldedunder position with respect to the remainder of the stream of fiap paper. The bottom surface of the folded under portion is then provided with a suitable bonding means and pressed into the stream of panel board by suitable press rolls. The stream of album cover board is then severed along the longitudinal length thereof into separate measured album cover boards.

Accordingly, it is an object of this invention to provide an album cover board with a multi-layer panel board 3 ,2 7 l ,05 l Patented Sept. 6, 1966 portion and spine board portion hingedly connected together and an integral flap portion.

It is another object of this invention to provide an album cover board having a multi-layer panel board portion with an integral flap portion.

It is another object of this invention to provide an album cover board having a multi-layer panel board portion with an integral flap portion.

It is another object of this invention to provide an album cover board which can be conveniently and economically constructed.

It is another object of this invention to provide a method of making an album cover which comprises the steps of generating continuous streams of panel boards, spine boards, hinge material and flap paper; bonding said hinge material stream to said panel board and spine board streams; folding under a portion of said flap paper stream; bonding said folded-under portion to a portion of said panel board stream; and severing said bonded streams into separate album cover boards.

These and other objects and advantages will become apparent from the following detailed description and appended claims taken in conjunction with the drawings, in which:

FIG. 1 illustrates a schematic plan view of an apparatus utilized in the making of the album cover board of this invention;

FIG. 2 illustrates a view taken at line 2-2 of FIG. 1;

FIG. 3 illustrates a cross-sectional view taken at line 3-3 of FIG. 2;

FIG. 4 illustrates 4-4 of FIG. 2;

FIG. 5 illustrates 55 of FIG. 2;

FIG. 6 illustrates 6-6 of FIG. 2;

FIG. 7 illustrates 77 of FIG. 2;

FIG. 8 illustrates a perspective view of an album cover board made according to this invention; and

FIGS. 9 to 11 illustrate perspective views of other embodiments of this invention.

Referring to the drawings, particularly FIGS. 1 through 7, the assembly machine of the invention comprises two side plate assemblies 20 and 21 which are maintained in spaced parallel relation by means of a plurality of cross bars or cross ties (not shown) and which are suitably supported above the level of the floor, for example, by a plurality of leg members. A pair of board material shafts 22 are rotatably mounted in the side plate assemblies 20, 21 near one end thereof in vertically displaced planes and a board material roll 23 is wrapped on each shaft 22. The board material 24 which is in strip form is made of material suitable for album cover boards. Further, the board material 24 is of a thickness which is of suitable flexibility for winding and is of a width slightly greater than the width of the spine board and panel board to be cut therefrom.

The board material strip 24 of the top board material roll 23 is passed over a suitable idler roll 25 which is rotatably mounted in the side plate assemblies 20, 21 and moved over a suitable glue roller 26. As the board material strip 24 moves over the glue roller 26, a sufficient amount of glue is adhered to the underside from a glue reservoir 27 by means of the glue roll 26. The glue containing board material strip 24 is then directed between a pair of press rolls 28.

a cross-sectional view taken at line a cross-sectional view taken at line a cross-sectional view taken at line a cross-sectional view taken at line The board material strip 24 of the bottom board material roll 23 is passed around a suitable idler roll 29 which is rotatably mounted in the side plate assemblies 20, 21 and directed to the press rolls 28. The press rolls 28 are rotatably mounted to the right of the board material shafts 22 in the side plate assemblies 20, 21 and are spaced apart vertically. The vertical spacing between the press rolls 28 is slightly less than the combined thickness of the two board material strips so that when these strips pass between the press rolls 28, a sufiicient force is applied thereto to press the board material strips together in bonded relationship so as to form a single adhered unit of two-ply board material.

A pair of cutter shafts 29 are rotatably mounted in the side plate assemblies 20, 21 in advance of the twoply board material stream. Each cutter shaft 29 has three cutting blades 30, 30', 30 fixedly mounted thereon which cooperate with the blades of the other cutter shaft 29 to simultaneously trim the edges of the two-ply board material strip 24 and sever the strip 24 into a twoply spine board strip 31 and a two-ply panel board strip 32. As shown in FIG. 3, the cutting blades 30, 30 perform the trimming operation on the board material strip 24 which reduces the strip to an exact width equal to the combined widths of the spine board and panel board required. The trimming operation further forms a fiat edge face on the two ply strip. The cutting blade 30" severs the strip 24 at the appropriate place to form the required sping board strip and panel board strip. A suitable guide means (not shown) is used to horizontally separate and align the spine board strip 31 and panel board strip 32 after the trimming and severing steps are completed. The strips 31, 32 are then directed between a pair of press rolls 33.

A hinge material shaft (not shown) is rotatably mounted in the side plate assemblies 20, 21 at a point below the plane of the two-ply board material strip 24 and a hinge material roll 34 is wrapped thereon. The hinge material 35 which is in strip form and relatively thin compared to the board material strip 24 is made of a light weight material which is suitable for adhesion to the board material. The hinge material strip 35 is moved over a suitable idler roller 36 and across a glue roll 37. As the strip 35 moves past the glue roll 37, a sufficient amount of glue is adhered to the top-side thereof from a glue reservoir 38 by means of a glue transfer roll 39 and the glue roll 37. The glue containing hinge material strip 35 is then directed between the pair of press rolls 33.

The press rolls 33 are vertically aligned and spaced apart a distance which is slightly less than the thickness of the two-ply board material stream. The lower press roll 33 is formed of a width equal to the width of the hinge material strip 35 and the upper press roll 33 is of a greater width so that the hinge material strip 35 is pressed into and made flush with the spine board strip 31 and panel board strip 32 upon engagement thereto. The hinged boards are then directed to a pair of press rolls 40.

A paper roll shaft 41 is rotatably mounted in the side plate assemblies 20, 21 above the plane of the two-ply board material strip 24 and a roll of paper 42 is wrapped thereon The paper 43 which is in strip form is of any suitable type which is sufiiciently flexible for forming into a roll and useful in album cover boards. The paper strip 43 is of a width greater than the width of the panel board strip 32 (approximately inch) for reasons as disclosed hereinafter.

The paper strip 43 is directed through a pair of guide rolls 44 which insure flatness of the strip 43 and delivered to a guide mechanism 45. The guide mechanism 45 comprises a suitable guiding means 46 for folding under the outer edge of the paper strip 43. The folded outer edge 43 can be of any desired width; however, for purposes of illustration 3 width between inch and A inch is selected. Further, the paper strip 43 may be formed with a score line or serrated line in order to more easily define and fold over the outer edge portion 43'. The folded paper strip 43 is then passed over a suitable idler roll 47 which is rotatably mounted in the side plate assemblies 20, 21 and moved across a glue roll 48 which is of any suitable width at least greater than the width of the folded outer edge 43' of the paper strip 43. As the strip 43 moves past the glue roll 48, a sutficient amount of glue is adhered only to the folded edge 43' as only the folded edge is allowed to contact the glue roll 48 from a glue reservoir 49 by means of a glue transfer roll 50 and the glue roll 48. The glue containing paper strip 43 is then directed between the pair of press rolls 40 and suitably guided into accurate alignment with the panel board strip edge.

As shown in FIG. 6, the press rolls 40 are vertically aligned and spaced apart a distance slightly less than the combined thicknesses of the two-ply panel board strip 31 and the folded paper strip 43. Such a spacing affords the creation of a firm adhesion bond between the panel board strip 31 and the folded outer edge 43 of the paper strip 43 so that a single album cover board strip 51 is formed.

The album cover board strip 51 is then transported to a suitable cut-off assembly 52 which generally comprises a cutter 53 and a cutter block 54. The cutter 53 is utilized in a synchronized manner with the remainder of the apparatus such that successive album cover boards 54 of equal length are severed from the album cover board strip 51. Such a cut-off assembly 52 is shown and described in our copending patent application Serial No. 246,966, filed December 20, 1962, now Patent No. 3,195,- 924 issued July 20, 1965.

Upon being severed from the album cover board strip 51, the album cover boards 54 are delivered to a suitable conveyor assembly 55 which is synchronized to the cutter assembly 52 to transport the cover boards 54 at a faster rate than the rate of feed of the album cover board strip 51 to the cutter assembly 52. This synchronism causes a spacing between successive album cover boards 54. The conveyor assembly 55 comprises an endless conveyor belt 56 mounted on a pair of conveyor rolls 57 which are rotatably mounted in the side plate assemblies 20, 21.

The conveyor assembly 55 subsequently delivers the album cover boards 54 to a suitable stacking device 58 wherein they are stacked.

Referring to FIG. 8, an album cover board 54 made in accordance with the above comprises a two-ply spine board portion 59, a two-ply panel board portion 60 spaced from the spine board portion 59, a hinge material portion 61 pressed fiush into and joining together the spine board portion 59 and panel board portion 60, and a paper flap portion 62 bonded to the panel board portion 60 and substantially covering the surface thereof. Such a structure is extremely important in padded album cover boards since the padding, for example, urethane foam, indented paper, etc., can be inserted between the paper flap 62 and the panel board 60 and extend to the inside edge of the panel adjacent to the hinged joint. This results in an attractive album cover.

Further, because the board material strips 24 are accurately trimmed and severed after being bonded together, the album cover board 54 produced possesses flat edge surfaces on all sides. Also, in view of the folding of the paper strip, a considerable reduction is made in the amount of glue used as well as in the amount of guiding necessary for aligning the paper strip on the cover board strip.

Referring to FIG. 9, a modified album cover board 63 which is constructed in a manner similar to that described above, comprises a two-ply spine board portion 64, a two-ply panel board portion 65 spaced from the spine board portion 64, a hinge material portion 66 pressed flush into and joining the spine and panel board portions 64, 6S, and a paper flap portion 67. The paper flap portion 67 is provided with a suitably glued edge area and pressed onto the hinge material portion 66, the edge face of the panel board portion 65 and an area of the surface of the panel board portion 65 adjacent the edge thereof.

Referring to FIG. 10, another modified album cover 68 which is constructed in a manner similar to that described above comprises a two-ply spine board portion 69, a two-ply panel board portion 70 spaced from the spine board portion 69, a hinge material portion 71 pressed flush into and joining the spine and panel board portions 69, 70 and a paper flap portion 72. The paper flap portion 72 is suitably bonded between the plies of the panel board portion 70 adjacent the hinged joint formed by the hinge material portion 71. Such a bond obviously imparts a more secure fixation between the paper flap and panel board portion than the above described embodiments; however, it is more difficult to obtain.

Referring finally to FIG. 11, another modified album cover 73 which is constructed in a manner similar to that described above comprises a two-ply spine board portion 74, a two-ply panel board portion 75 spaced from the spine board portion 74, a hinge material portion 76 joining the spine and panel board portions, and a paper flap portion 77. The hinge material portion 76 is pressed against the spine and panel board portions so that it is pressed flush into the panel board portion 75 and across the whole surface of the spine board portion 74 while the spine board portion 74 is being compressed by an amount equal to the thickness of the hinge material portion 76. The paper flap portion 77 is suitably bonded to the entire upper surface of the spine board portions 74 and a small area of the upper surface of the panel board portion 75. This album cover board 73 may be utilized in much the same way as the album cover board 63 of FIG. 9; however, the padding" cannot extend under the paper fiap portion 77 as far.

It is noted that the process of making the above described album cover boards utilizes a synchronized apparatus so that all operations are performed continuously upon the continuously generated strips of board material. Such an apparatus is similar to that described in our above-mentioned copending application.

Having thus described the invention, it is not intended that it be limited to the precise details described, as changes may be readily made in carrying out the invention without departing from the invention.
